\JOMLBINED CGAL AND GAS RANGE.

To all whom it may contact:

Be it known that I, PAUL BECKER, a citizen of the United States,residing at:Gleveland, in the county of Guyahoga and-State of Ohio, haveinvented new and'useful Improvements in, Combined Coal and Gas Ranges,of which the following is a specification.

My present'invention pertains to coolcing' ranges of thecombmed coal andgas type and more particularly to. such ranges .as

have a depressed chamber in communication with the ovenat the front ofthe oven bot-- The-object of my: invention is to improvev the kind of"ranges set forth, by the provision of a connection intermediate thedeflector and the closure-plate of the burnerchamber, whereby. movementof the deflector will be attended by movement ofthe closure plate.

Inthe present and preferred embodiment of my invention, theclosure-plate and the deflector are so relatively arranged and conward"and'forward'to establish communicanectedthat-when the deflector is-movedrearwardly the closurepla=te will be moved uption between theburnerchamber and'the space between the: oven bottom and the deflectorand at the same time close the forward end of said space; so as tovprotectthe operator from: a flare of the ignited gas, while when thedeflector is drawn forwardly, the closure-plate will be moved rearwardlyand downwardly to close the burner chamben and isolate the same fromthespace below the deflector. all as hereinafter described and'claimed, andillustrated; in the annexed drawings, in which:

Figure 1 is aplan of so much of a range:

construction as is necessary toillnstrate the best practical embodimentof! my invention that Ihave as yehdevised; Fig.- 2 is-at verticalsection showing the closnreplaite: n in position to establishcommunication between the burner-chamber and I the" space in the-ovenbelow the: deflector. Fig: 3 is a Specification of Letters Patent.

view similar. to :Fig; 2, but with the closureplate and the deflectorindifierent positions, namely. to isolate-the burner-chamber from thespacebelow the deflector and to leave the said space open at its forwardend. Fig. 4 is. a front elevation of the structure with themovable-parts in the same positions as in Fig. 3'.

I Similar numerals of reference designate corresponding parts 1n all ofthe views of the -d raw1-ngs.-

In furtherance of my invention. a chamber 1. is arranged below thebottom 2 of the oven, at" the forward endthereof, and -in said chamberis positioned a gas burner 3' that. extends lengthwise. of fthechambera-nd is designed to be supplied with gas from a suitable sourceof supply.

For closing the chamber 1 when coal is to be used as fuel, a plate 4 isprovided. In its horizontal, closed position this plate 4 effectuallyisolates the chamber 1 and the burner 3 from the oven and protects theburner against injury. The said closure plate 4 is carried by arms 5which are connected with the oven in such manner that they are adaptedto swing and move vertically within certain limits.- The arms 5 areformed integral with-or are otherwise fixed to the plate 4 so as toassure the-arms and the platemoving as aunit, and, by preference, eachof the arms is provided with a segmental rack. 6.

Movable forwardly and rearwardly in and supportedbyguideways- 7 on theside walls ofst-heoven, is adefl'ector 8. and said deflector: isprovided by preference with two racks 9, one for cooperation with-eachseg- ,mental rack 6, From this itfollows that when the deflector isdrawn "forwardly, the vplate 4: will be moved from its vertical positiondownwardly andirearwardly into its horizontal position inwhich itclosesthe passage from the burner-chamber to the oven, while when. the:deflector is: moved rearwardly, the plate 4 will be movedfrom;its.horizontalposition upwardly and for nited-andalsoservesto prevenhtoa certain extent-the escape of-the heat and other-prodiuctsx ofrcombustion from: the forward end 3 of the space between the oven bottomand the deflector.

The rear portion of the deflector 8 is preferably, though not nectssarily, provided with suitable apertures as 10 to facilitate thepassage of products of combustion given oil by the gas burner from thespace below the 'leflector to the space above the same? A, best shown inFig. 3 the guideways 7 are. gradually increased in height toward theforward end of the oven. By virtue of this construction it will bemanifest that the guideways permit of slight vertical movements of thedeflector incidental to the forward and rearward movements thereof as isnecessary to the free operation of the cloaure-plate by the deflector,and this without permitting the upward passage of products of combustionpast the side edges of the deflector.

While I prefer to employ a segmental rack on each arm of theclosure-plate and two complementary racks on the deflector, I desire itdistinctly understood that without involving departure from the scope ofmy claimed invention,-a single segmental rack on one arm 5 and a singlerack on the ole fiector may be employed.

While I have restricted the construction illustrated to the elementscomprised in my invention it is to be understood that when the inventionis embodied in a combined coal and gas range, the range may be andpreferably is provided with such of the usual appnrtenances as are notincompatible with the purpose of the invention. When desired adetachable implement 11, fitted in an aperture of the deflector may beemployed as shown in Fig. 1 to facilitate movement of the deflector.

It will further be gathered from the foregoing that. in the positionshown in Fig. 2, the ClOSulQ plate at will preclude the possibility ofthe person or clothing of the opera tor contacting with the flame fromthe burner 3 when the operator is placing coolo ing utensils inorremoving the same from the oven space above the deflector 8.

' While I prefer to employ means for assuring movementofeither theclosure plate or the deflector on movement of the other, I do not desireto be understood as confining myself to said provision.

Having described my invention, what I. claim and desire to secure byLetters-Patout is:

1. In a combined coal and gas range, an oven, a chamber extendingdownwardly from the forward portion of the ovenbottom, a gas burner insaid chamber, guideways on the sidewalls of the oven; said guidewaysbeing gradually increased in height toward the forward end of the oven,a closure plate for the chamber,'mounted in the oven to swing and movevertically and novasee having a segmental rack, and a deflector spacedabove the oven bottom and movable rectilinearly and vertically in theguideways and having a rack internieshed with the seg= mental rack ofthe closure platea 2. In a combined coal and gas range, an oven, achamber extending downwardly from the forward portion of the ovenbottom, a gas burner in said chamber, guideways on the side walls of theoven; said guideways being gradually increased in height toward theforward end of the oven, a movable closure plate forothe chamber,deflector movable rectilinearly and vertically in the guideways, andconnection between the deflector and the closure plate for moving thelatter by the former.

3. in a combined. coal and gas range, an oven, a chamber extendingdownwardly from the forward portion of the oven bottom, 21 gas burner insaid chamber, guideways on the side walls ofthe oven, amorable closureplate for the chamber, a deflec' tor movable forwardly and r arwardly inthe guideways, and connection between the deflector and the closureplate for moving the latter "he former.

i. In combined coal and gas range, the combination of an oven, a burnerchamber extending downwardly from the bottom thereof, a gas burner insaid chamber, a movable deflector spaced above the oven bottom, amovable closure-plate constructed and arranged in one position to closethe chamber and in another position toclose the space between the ovenbottom and the deflector, and a. connection intermediate the deflectorand the closure plate, whereby movement of one will lie-attended bymovement ot'the other.

5. In a combined coal and range, the combmation of an oven, a burnerchamber between the oven bottom and the deflector,

a rack on-the deflector, and a segmental rack on the closure plate andintermeslied with the rack on the deflector. F

6. The combination in a range, of an oven, a burner chamber extendingdownwardly from the forward portion of the oven bottom, a movabledeflector spaced above the oven bottom, a movable closure plateadapted'in one position to close communication between the chamber andspace, and in another position to close the forward end of the space,and a connection intermediate the deflector and the closure platewhereby movement of one moves the other.

7. In a range, the combination of an oven, :1 burner chamber, movabledeflecting-means in the oven, movable means for controlling Copies ofthis patent may be obtained for gas burner in said chamber, and amovable closure plate that in one position closes the burner chamber tothe space below the de fiector and in another position closes the for-Ward end. of said space.

In testimony whereof I have hereunto set my hand. in presence of twosubscribing wit- 'nesses.
